(Joachim, for some reason, on each of my four days in Frisco i missed having you there. Likely means you're an addictive bloke to spend time with, can you say hello to the similar unique Martina for me)

Jacko, hope to see you at ETF. I say hello to Martina. We miss you too. I would like to be in San Francisco too. Actually i am quite often there. I am designing speakers and electronics for Spiral Grove - Canalis in Berkeley. I also visit Siegfried Linkwitz a lot.
Jose and Ricardo. I use FMs mostly in PSUs. I also use FC when i cam not find the right value. Sometimes it must by a Nichicon Muse or Elna Silmic2. There is a company in Germany called Frolyt that also makes good elcaps. They have a bipolar series for audio.
Check out the website.

I found an interesting circuit by JC Morrison that is a Fet-Tube folded cascode. It can be used as an input stage for an MC pre-pre. He claims that it sounds better ( less Hifi, better for classical ) then a series Fet-tube cascode ( Arthur Loesch circuit for example ). He reasons that the idle current can be set more optimally and independently in the Fets and the tubes. Running a series Fet-Tube cascode on 35mA would certainly cause some trouble and lots of heat. With 200V that would burn 7W.
